Component Containment and Hierarchy

Canvas hierarchy in the DOM is defined via parent and child relationships.

These may be set up explicitly via APIs such as Canvas.addChild(), or may be automatically set up by composite components. For example TabSets will nest their panes inside an appropriate sub component.
Developers using the autoChildren subsystem may also use the autoParent attribute to specify a target parent.

In addition to parent-child relationships, Smart GWT components support master-peer relationships. When a canvas is set to be the peer of some other canvas, the master and peer will share the same parent canvas (reparenting a master will automatically reparent any peers). Peers will move, resize and redraw with their masters and commonly use snapTo positioning
